Internal hose degradation and environmental wear are common causes of pressure loss, uneven caliper response, and dangerous fluid leaks in hydraulic brake systems. Replacing aging or damaged calipers with this PowerStop Autospecialty OE Replacement Brake Caliper restores optimal hydraulic response, eliminating internal line expansion under heavy braking conditions and ensuring consistent caliper actuation. This upgrade is critical for maintaining safe stopping power and hydraulic integrity in demanding fleet operations.
Constructed with high-quality materials and assembled with new seals, guide pins, dust boots, bleeder screws, and stainless-steel hardware, this caliper offers superior durability and performance. The high-temperature EPDM rubber dust boots prevent debris ingress and withstand extreme heat, while the pressure-tested assembly guarantees reliable brake operation. Designed as a direct bolt-on replacement, it fits seamlessly without modifications, providing a hassle-free installation for both professional and DIY mechanics.

Expert Installation & Field Note
Our shop experience specializing in heavy-duty brakes since 1985 emphasizes the importance of proper hose routing during installation. Ensure hoses are routed to prevent chaffing against chassis components and allow full twist clearance during steering cycles. Always check line mounting brackets on heavy commercial frames for secure fitment, as improper mounting can lead to premature failure or fluid leaks.
